domma-js@0.50.0
Dynamic Object Manipulation & Modeling API - A complete front-end toolkit.
AI Security Review
scanned 11d ago · by lpm-firewall-aiThe package’s install hook can write first-party guidance and settings used by Claude Code into the consumer project, so this warrants a warning under the agent extension lifecycle policy. The interactive prompt, existing-file checks, and absence of a demonstrated malicious payload do not support blocking publication.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
npm installation runs the postinstall hook, which prompts the user; alternatively, the user can run the setup-ai CLI command.
Impact
Claude Code may receive package-provided Domma project guidance and settings in that project.
Mechanism
The hook copies CLAUDE.md, .claude/, and related project files into the project root when the user proceeds and the destinations do not already exist.
AI rationale
The package’s install hook can write first-party guidance and settings used by Claude Code into the consumer project, so this warrants a warning under the agent extension lifecycle policy. The interactive prompt, existing-file checks, and absence of a demonstrated malicious payload do not support blocking publication.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json runs bin/postinstall.js during installation.
- bin/postinstall.js offers Claude Code files and copies them into the consuming project after an interactive prompt.
- The copied CLAUDE.md provides Domma framework guidance; the observed content does not establish credential access or remote control.
- bin/domma-cli.js also exposes setup-ai as an explicit user command.
Evidence against
- The postinstall asks whether to copy the files and skips when the user answers no.
- The copy logic preserves existing CLAUDE.md and .claude/ paths.
- The inspected code shows no network endpoint or credential transfer.
